Eric Barnes[email protected]CTStress leads to more heart attacks among police, firefightersPolice officers and firefighters are far more likely than the general population to suffer heart attacks or sudden cardiac death on the job. But their coronary CT calcium scores don't differ all that much from those of the general population, according to a study presented at the American College of Cardiology meeting in Atlanta.March 14, 2010CTVC CAD: Projection-based features reduce false positivesAn advanced visualization method for virtual colonoscopy could help computer-aided detection (CAD) programs slash false-positive rates, according to researchers from the State University of New York at Stony Brook and colleagues.March 9, 2010CTOrgan-based tube-current modulation cuts breast doseVIENNA - Radiation doses to the breast can be cut by nearly 40% using a new organ-based dose modulation technique in combination with a noise-optimized image reconstruction method. The two techniques must be used together if the resulting images are to remain readable, researchers reported.March 7, 2010CTOne-day bowel prep eases VC for patients, providersVIENNA - A one-day bowel prep and virtual colonoscopy exam regimen offers sufficiently good image quality, making life easier for both patients and providers compared to a multiday regimen, according to a study presented Sunday at the European Congress of Radiology.March 6, 2010CTCT doses, widely variable in Europe, are reduced by staff effortsVIENNA - Although dose variations remain wide on the continent, there are opportunities for substantial improvement with dose-reduction training and programs, according to two European studies of clinical CT doses presented back-to-back Saturday at the European Congress of Radiology.March 5, 2010CTCoronary CTA predicts long-term outcomesVIENNA - A decade's worth of coronary CT angiography (CTA) studies is starting to reveal the modality's long-term predictive powers, if a study from one of Poland's largest heart centers is any indication.March 5, 2010CTHigh pitch equals low dose in coronary CT angiographyVIENNA - High-pitch dual-source CT exams can evaluate the coronary arteries using about a third of the dose of even prospectively triggered exams, according to a study presented in Thursday's cardiac sessions of the European Congress of Radiology.March 3, 2010CT320-row CT minimizes dose in pediatric abdominal studiesIt's no secret that CT radiation dose levels in children -- especially in the emergency department, where patients are fidgety and physicians need fast answers -- are too high. One solution, investigated by researchers from Toronto and Berlin, is wide-area-detector scans with 320-detector-row CT.March 2, 2010Nuclear MedicineSPECT more costly, less effective than CTA for chest painCoronary CT angiography (CTA) is the most cost-effective way to diagnose patients with chest pain and suspected coronary artery disease, according to a new study in the March issue of Radiology.March 1, 2010CTObama gets virtual colonoscopy, keeps presidential powersAs part of his first annual comprehensive physical exam as chief executive, U.S. President Barack Obama underwent a virtual colonoscopy exam that found him free of colorectal polyps or cancer, chief White House physician and Navy Captain Dr. Jeffrey Kuhlman told reporters Sunday.February 28, 2010Previous PagePage 129 of 258Next PageTop StoriesDigital X-RayChest x-rays reveal atherosclerosis in patients undergoing amputationsLower limb amputation is an increasingly common major complication of advanced peripheral arterial disease and diabetes mellitus.MRI3D MRI technique helps plan treatment for pediatric heart conditionsWomens ImagingCould AI scoring help with managing DCIS?CTClinicians, beware: CT diagnostic accuracy varies by adnexal lesion typePractice ManagementRadiology coding update for 2026
